A couple questions regarding this tuner. You said it could hold multiple tunes on the device, is it pretty easy to switch between tunes. The Jeep is my wife's daily driver and i don't think that she should have that much power at all times and would like her to have a better MPG. My father also has an 05 WK with the HEMI, can he share the same tuner or would he have to purchase his own? Since the tuner I saw were expensive it would be easier if I could split the cost with someone else. These are just some questions that came up off the the top of my head and not sure if they are reasonable or even if they are applicable.
The tuners become VIN locked once used and can't be used on another vehicle until the first car gets put back to the stock tune. It holds 3 tunes plus the backed up stock tune on SCT. It is easy to change tunes but takes a few minutes to do.
Sean who sels and makes the tunes for SCT and Diablo can be reached at Hemifever@aol.com
He can tell you if your vehicle is supported or not. The actual tuner for the 4.7 is a SCT 9550.
